Minor Description
Hi dear team:
I'm developing OLAP Platform based on Kylin2.5.2. During my work, I found that kylinProperties.js:37(getProperty(name)) can't get the property of the first line in the '_config' which initialized through /admin/public_config.
For example, the public config is 'kylin.restclient.connection.default-max-per-route=20\nkylin.restclient.connection.max-total=200\nkylin.engine.default=2\nkylin.storage.default=2\n
kylin.web.hive-limit=20\nkylin.web.help.length=4\n'. I expected to get 20 but got '' when I want to get config by key 'kylin.restclient.connection.default-max-per-route'. This problem caused by 'var keyIndex = _config.indexOf('\n' + name + '=');'(at kylinProperties.js:37) return -1 for those names before which don't have an \n(at the first line).
Then, I debug the AdminService.java, KylinConfig.java and found that the KylinConfig.java:517(around this line, in method exportToString(Collection<String> propertyKeys)) build the public config string with a char '\n' after each property, which cause the first property don't has '\n' before it.
Those are what I found, which will cause problem for developers.
How do you think?
Best regard
